HEBHANNI'THOBENS, B. A., OF STE-CROB, SWITZERLAND PYBOPHOBIG LIGHTERApplication led H9101! 1B, 1931, Serial No. 523,097, in Germany April14, 1930.

This invention relates to pyrophoric lghters. the pocket type in which afuel suppli wick is ignited by means of cooperating friction wheel andpyrophoric element. While lighters of this class are'very convenient tolight cigars and cigarettes, itis diiiicult to veniently introduced vfrom the lower rear side of the casing to-j light pipes because .thefiame on the end of the wick which ordinarily is situated' in proximityof the lighter bod cannot be introduced into the interior of t e pipebowl.

The object of the invention is the pro-v vison of a pyrophoric lighterhaving a movable wick holder so that after ignition of the' wick theholder can` be displaced to bring the end of the wick into a positionwhere it projects a considerable distance beyond the lighter body andthev fiame can be coninto the interior of the pipe bowl.

In the accompanying drawing, Figure 1 shows a lighter according to theinvention with the wick in ignitingl position.

Figure 2 shows the lighter with the wick holder projecting beyond thelighter bod Figures 3, i and 5 illustrate the wic `holder displacingmeans with the holder in different positions.

, Figure 6 1s a sectional elevation cia modification.

Figure 7' is aA section along the line of :Fig 6.

ylihe lighter .according to Figures 1 to 5 I comprises a casing 1 uponwhich is rotatably mounted, by means of a hinge 2, a cover 3. When thiscover is opened it actuates. 1n well known manner' the friction wheel 6by means of a 'hook i which is rotatably mounted on the cover at 5. 7 isthe pyrophorusst'one.

rihe wick 8 is contained in a tube 9 `which can slide within a tubularguide 1G provided in the. casing 1 and which guide 1s inclined wards theupper vfront side. The tube9 is provided with a rack 11 which mesheswith a pinion 12 of which a s p ortion projects .through the wall of thecaslng, so that the pinion can be turned by means of a finger of thehand in which the lighteris held.4 The tube 9 is .also provided withseveral circular grooves 13 situatedtbelovvr the rack 11 and with aflattened portion 14 at the end of the 1` by means of laf stroke in theinterior of the casing and the I free end 15 of the wick is adjacent tothe friction wheel 6 as shown in Figure l. When a pressure is exerted onthe push button 16 the cover 3 is freed and opened under the action of aspring which is not shown. .Opening of the cover actuates the frictionwheel and sparks, are produced which ignite the end 15 of the wick.

if one desires now to light a pipe, the wheel 12 is turned by a nger ofthe hand in which the lighter is held, so as to raise the tube 9.Yas'far as the rack 11 permits. The end 15 of the wick takes then theposition shown in Figure 2 in which it projectsl'aterally bevond theedge of the casing, and can be easily introduced into the bowl of thepipe to light the tobacco. s

rihe tube 9 is adapted to be completely removed from the lighter body 1for changing the wick for instance, and for this purpose the tube 9 isturned for half a revolution while one of the v,circular grooves 13meshes with a` tooth of the wheel 12, so that theiiattened port-ion 11i,arrives on the side of the wheel 12 (Fig. 5) vwhereupon the tube 9 canbe pulled out of the 'guide 10. To put the Ftube back in vplace one willproceed in analogous manner. ,Y l In the modification shown in Figures 6and 7, the toothed wheel 12 is yieldingly held in a cap 18(engagedbetween the side walls of .the casing 1. A shaft 19 traverses the wallsof the casing, the cap 18 and the wheel 12 and'is providedatone of itsends with a Y has been loosened and the shaft 19 removed, the ca 18Aandthe wheel 12 can be ulled out from t eir recess in the lighter bo y.

2. In a pyrophoric pocket lighter having a casing forming a fuelreservoir, wick i niting means mounted on the casing, a tu ular guidemember extending from the upper end of the lighter casing into theinterior thereof, a longitudinally movable wick tube removably -fittedin said tubular guide member, manually operable. means for raising saidwick tube along said guide member into a osition in which the upper endof the wick tu overhangs one edge of the casing and means for operatingsaid wick igniting means when the wlck tube is in its lowermostposition.

3. In a pyrophoric pocket lighter having a casing forming a fuelreservoir, wick igniting nmeans mounted on top of the casing, alongitudinally movable wick tube slidably mounted in the casing andrejecting through the top thereof, a cover ingedly mounted on thecasin'g and adapted to close over the top thereof, said cover beingoperatively connected to said wick igniting means whereby opening of thecover will actuate said igniting means, and manually operable means forralsing said wick tube into a osition in which the upper end of the wietube lprojects beyond the periphery of the casing when thecover is inopen position.

4.
